Said pillar resident of Lewisburg, in the county of 1 supportsan end portion of a horizontal bed Union and State of Pennsylvania, havein- A, and an end portion of said horizontal vented a new and ImprovedMachine for bed, or that end which is adapted to sup- Inserting DiagonalStrands in \Vovcn-Cane y port the working portions of the machine,Fabrics, of which the following is a full, is in the form of adiamond-shaped table, clear, and exact description. 1 the points whereofextend in direction of The purpose of the invention is to prothe ends ofthe bed and in direction of the Vide exceedingly simple, positive andefi'ecfront and back thereof, as best shown in Fig. tive means fordepressing the warp strands 2. In fact, an outer point of the table 12and raising the weft strands in woven cane constitutes the working endof the bed, and fabric for the passage of a needle carrying a at theopposite end portion of said bed a diagonal strand, and to accomplishthe oblongitudinal slot 13 is made. At the exject by the joint downwardmovement of a tremity of the slotted end of the bed a bar carrying guidepins for the fabric and grooved pulley 14 is mounted to turn horiaparallel bar carrying depressingfingers for zontally upon the bracket 15offset in dithe warp strands in connection with autm rection of thefront of the machine from matically acting fingers that receive and thesaid bed, as shown in Figs. 1 and 2. hold elevated the weft strands.

A second proved machine; Fig. 2is a plan view therehorizontal peripherally grooved pulley 23 is of;Fig. 3 is a longitudinal vertical section supported at the outer endpoint of the table taken practically on the line 3-3 of Fig. 2; 12 bymeans of a bracket 24 attached to the Fig. 4 is a transverse sectiontaken substantable; and said pulley 23 is secured to a tially on theline 4 4 of F ig. 1; Fig. 5 is a shaft 25, which extends down throughthe transverse section taken practically on the arm 24 and through abracket 26 located line 5-5 of Fig. 1; Fig. 6 is a detail view below thesaid table 12, as is shown in Figs. of the stop employed in connectionwith 1 and 3, and said shaft 25 is provided with the operating mechanismfor the elevating an attached pinion 27 fingers for the weft strands;Fig. 7 is a lon- A sliding rack C is mounted for movegitudinal sectionthrough a portion of the ment at the forward inclined portion ofpin-carrying bar and cane fabric, showing the table 12, said rack havingmovement the warp strands depressed and the weft to and from the pinion27, which pinion is strands elevated; and Fig. 8 is a plan view engagedby teeth 27 formed on the rack. of a piece of cane fabric, illustratinga few said sliding rack at its inner end being of the diagonal strandsapplied. provided with a handle 28. The rack is preferably L-shaped incross section, and the teeth 27 are in its horizontal member; itsvertical member is provided with longitudinal slots 29 which looselyreceive bolts 30 or their equivalents, that extend into the said table,thus guiding the said slide. The movement of the said sliding rack Ccontrols the movement of the needle B. and this is accomplished by meansof an endless belt 31 that passes around the pulleys 1H and 23, and isattached in any suitable or approved manner at one of its stretches tothe upper end of the needle-operating arm 16 as is best shown in Fig. 1.

A slot 33 is produced in the lower portion of the pillar 11, and throughthis slot a foot treadle or lever 33 is passed. being fulcruined at therear of the said pillar and extending beyond its front. Said leveroccupies a diagonal position relatively to the front portion of thebase, so that the operator will have ready control of the sliding rackC. \Vithin said pillar this lever is connected by means of links 34 witha beam 35, which beam extends out through slots 36 in direction of theends of the machine. and said beam 35 occupies a position at. an angleto the trcadle 33 and at a slight angle to the bed A. The beam 35 isheld in an upper position by means of springs 37 attached to the pillar11 and having upward hearing at the end portions of the beam as is shownin Figs. 1 and 3.

A bed plate 38 is located over the central portion of the table 12,extending in direction of the ends of the machine, and said bed plate isspaced apart from the table 12 by means of a. supporting bar 39, whichis more or less diagonally located relative to the said bed plate and islonger than the bed plate, extending beyond its ends. In fact. thesupporting plate 39 extends practically from one corner of the bed plate38 to the opposing diagonal corner. The said supporting plate 39 has itsupper end portions recessed or cut away as shown at 40 in Fig. 3. Atopposite sides of the supporting plate 39, at its ends, two sockets 41are formed, which sockets are secured also at their upper ends toopposite diagonal corners of the bed plate 88 as is best shown in Fig.2.

A guide plate D is located above the bed plate 38. and is spaced aparttherefrom, the said guide plate D being preferably transversely arched.its upper face being its convexed face. and the weft cane fabric H ismade to rest upon this guide plate D while the diagonal strand H isbeing passed through the said fabric by means of said needle B. Theguide plate D is provided with a series of upwardly-extending pins 42.Said pins are in two rows and are staggered in their generalarrangement. the pins of one row being opposite the center of the spacesbetween the pins of the opposing row as is indicated in Figs. 4, 5 andT. The needle B in operation passes over said guide plate D whichlikewise may be termed a pin plate, passing between the rows of pins andthrough a suitable guide 6 located at the inner end of the said guideplate as is illustrated in Fig. 3. The guide plate D is further providedwith a series of transverse centrally located slots 43, and said slotsare so located that they are between two diagonally opposing pins 4-2 onsaid guide plate D as is best shown in Fig. T. so that a pin of one rowand a diagonall opposite pin of the opposing row will be located betweeneach two slots. The pins 42 are adapted to pass up through the meshes inthe woven cane prior to a diagonal strand being woven therein. The saidguide plate D is held yieldingly spaced apart from the bed plate 38 bymeans of downwardly-extending bolts -14, two of which are usuallylocated adjacent to each end of the said guide plate. and said bolts areloosely passed through suit able openings in the bed. plate 38, and areprovided with nuts 46 at their ends, so as to limit the upward movementof the said guide plate. Springs 45 are coiled around said bolts 44between the two plates 38 and D, the spring serving to return the guideplate D to its normal position after having been relieved from pressure.

A depressing plate or bar E is located above the guide plate D; and saiddepressing plate 15 is provided with a series of downwardly-extendingfingers 48 arranged to enter the spaces between diagonally opposing pins4-2 to press and hold down the warp strands of the fabric when thedepressing bar is carried downward taking with it the guide bar D. Inorder that the fingers 48 shall not slip during such operation a recess49 is made in the bottom of each finger 48. capable of receiving astrand of the fabric. As the depressing plate E is forced. downward todepress the warp strands, retaining hooks F extend upward and rearwardthrough the slots 43 in the guide plate D, which hooks receive and holdelevated or raised the weft strands adjacent to the pins 42?, as isshown best in Fig. 7; and at such time the needle B in passing betweenthe rows of pins 4-2 will pass likewise between the depressed warp andthe elevated weft strands, and thus weave the diagonal strand carried bythe needle through the body of the fabric as is shown in Fig. 8, whereinthe fabric is designated as H and the diagonal strands as H. Theseretaining hooks F are pivoted upon. two brackets 50 rigidly secured. tothe body plate 38 as is shown in Fig. 3, and each retaining hook Fprovided with a reduced foot section just below its pivot, and said footsections 51 enter recesses in the upper edges of curved cradle bars 52,the upper ed es of which bars are more or less concave as is shown inFig. 5, for one bar. These cradle bars 52 are held properly spaced andhave concerted action by front and rear tie rods 53 and 54, and sprlngs55 secured to the table 12, or the supporting bar 39 at its rear, arecarried up over the bed plate 38 to an engagement with the undersurfaces of the said tie bars 53 and 54 for the purpose of keeping thecradle bars up to their work with reference to the hooks F. The normalposition of the retaining hooks F is that shown in Figs. 4 and 5,wherein it will be observed that they are slightly below the upper faceof the guide plate D, which is in its upper or normal position, and thatthe hooks have an upward and a forward inclination, whereupon bylaterally moving the cradle bars 52 in a forward direction the said barscause the said retaining hooks to assume a vertical position, saidposition being assumed as the guide plate D is carried downward, thuscausing the said hooks to catch and receive the weft strands and holdthe same elevated as the fingers 48 on the depressin plate E engage andhold the warp strands epressed. The movement of the cradle bars 52forward and rearward is automatically accomplished preferably in thefollowing manner: Rearwardly-extending links 56 are secured to the reartie bar 54, usually at its end portions; and these links 56 are attachedto a connecting rod 57, and said connecting rod is pivotally connectedwith downwardlyextending links 58. Said links in their turn are securedto a crank shaft 59, mounted to turn in suitable bearings 60 supportedby the table 12, the crank arm 61 of the shaft 59 being given an upwardand somewhat of a forward inclination as shown in Fig. 1. The shaft 59,which has a rocking motion, is limited in such motion by producing acurved slot 62 in one of the bearings 60 as shown in Fig. 6, andsecuring a downwardlyextending crank arm 63 to said shaft 59, thehorizontal member of which crank arm has movement in the slot 62. Themovement of the crank shaft 59 and the operation of the cradle bars 52are accomplished by carrying the front or forward end of a lever arm 64beyond and beneath the front or forward side edge of the bed plate 38through one of the openings 40 in its supporting plate 39 as is shown inFigs. 1 and 3. This lever arm 64 is preferabl given a compound curve,and its rear en is pivoted to a standard 65 carried by the table 12 asbest shown in Fig. 4, while a curved link 66 is attached to the leverarm 64 and to the upper end of the crank arm 61, the curvature of saidlink 66 being in direction of the forward or front side of the machine.The forward or front end of the lever arm 64 is received in a recess 67,produced at one side of the lower end of a trip finger 69 that issecured to the depressing plate E and extends down at the front orforward side portions of said depressing plate E, the guide plate D andthe bed plate 38. The depressing plate E is operated through the mediumof the treadle 33, and to that end downwardly extending rods 70 areattached to the end portions of said depressing plate E, which rods passdown through the sockets 41 and the table 12 to an engagement with theouter end portion of the beam 35.

In the operation of the machine, the parts being in their normalposition best shown in Figs. 1, 3, 4 and 5, the cane fabric H. isthreaded over the pins 42 on the guide plate D and the treadle 33 ispressed downward, which will carry the beam 35 down, placing its springs37 under tension, and will also cause the depressing bar or plate E tobe drawn downward until its fingers 48 engage with the weft strands ofthe fabric, whereupon the said plate E is continued downward until theguide plate D is depressed against the tension of its springs 45 farenough to uncover the upper ends of the retaining hooks F, bringing suchportions in such relation to the weft strands of the fabric that whenthe hooks are moved rearward they will engage with said weft strands.Such rearward movement is brought about approximately when thedepressing plate E has reached the limit of its downward travel byreason of the operating arm 69 forcing the front end of the lever arm 64dowlr ward, thus pushing forward the connected cradle bars 52, therebybringing all of the hooks F to an upper position, causing them toreceive and hold elevated the weft strands. While the treadle 33 is yetdepressed the slide 0 is operated past the needle B over the guide plateD between its rows of pins 42 and consequently above the warp strandsand below the weft strands as is shown in Fig. 7. An end of the diagonalstand H is now passed through the eye of the needle B, as is also shownin Fig. 7. The operating mechanism for the needle is now reversed,carrying the needle back to its normal position and causing the attacheddiagonal strand to be drawn through the path of the needle. \Vhen thisis accomplished the diagonal strand is caught in any desired manner, andthe treadle 33 is releasedqvhereupon the springs 37 act to force thedepressing plate E upward, and the operating arm 69 rocks the front endof the lever arm 64 upward, thus restoring the confining hooks F totheir .normal position, and at the same time the springs 45 restore theguide plate D to its normal position. The fabric H may now be shifted toreceive another diagonal strand, and the operation of the machine isrepeated, as described.

It may be here remarked that the shafts 5T and 59 belonging to thecontrolling mechanism for the hook retaining devices F are steadied intheir action by means of a spring f, shown in Figs. and 5.
